Abstract: This study investigates the performance of hybridised micro-grids based on solar PV supplemented by Internal Combustion Engines (ICE). Three different battery technologies (lead acid, lithium-ion, and vanadium redox flow) as well as the effects of load demand scalability are considered. The optimisations are based on Cost of Energy (COE) but the analyses consider several performance indicators including Excess Energy (EE), Renewable Penetration (RP), and Duty Factor (DF). Optimisations are done using the software tool HOMER (Hybrid Optimisation Model for Electric Renewable) and consider systems spanning 10 to 50 houses (210 kWh/yr to 1050 kWh/yr) and subject to modelling featuring hourly temporal resolution. A sensitivity analysis is also conducted to see the effects of various input parameters on the Cost of Energy.
